Top Questions from OKmarts Buyers
Q: Are there any hidden fees, handling charges, or unexpected export tariffs added to the final invoice?
A: Our pricing is transparent. Line items for product costs and shipping fees are explicitly detailed at checkout. Local import duties, VAT, or regional consumption taxes are typically the responsibility of the importer of record unless a DDP (Delivered Duty Paid) arrangement is pre-negotiated.

A: OKmarts procures components directly from authorized manufacturers and verified tier-1 global distributors. Every product undergoes rigorous inbound inspection, featuring factory serial number tracking and original packaging verification to prevent any counterfeit or refurbished goods from entering the supply chain.
